It will be, seenthat the brlaoket constitutes efi'ective means for at the same time fastening the abuttiiig fbeems' together f id min r n S pp ingmeehs and the motor 21ereclearlys'hown Figure? B'y placing the' balttery' at the front of the jreari axle and the motor at the rear, an advantageous distribution of weight on'such rear axle is .secured and proper space is provided for the'placeme'ntof the The arrangements of the battery supporb adj ustedby a construction of the frame hereinafter to'be more particularly described. Figures 3 and 4 show indetail'the construction of the supporting frame 23, and also the arrangement of the driving meclui nism. As illustrated in these two figures, 25 is a motor casing of anyimproved construction, which motor is as before set forth, su ported on one side by springs from the b0 y of the vehicle, and on the other side by the frame 23. The frame 23 is, connected to the side of the motor by the T-shaped portion 25 provided with the bolts 26, and the other end of the frame is provided with .two arms 25'? which are connected to the axle of the vehicle by means of the bolts 27 passing through slots 28 in the arms 25. This bolt and slotconnection permits of a movement of the motor toward and away from the axle to provide for the adjustment of the chain. As shown in Figure 4, the axle 28 is of angular shape, and is surrounded by a journal member 29 to which the split bearing 30 is secured by the two bolts 27. The upper" part, of the bearing is'provided with the lug 31'into which the reversely threaded bolt 32 takes at one end. I The other end of the threaded bolt is threaded into the part 33 projecting downwardly from the frame 23., The nut 34 secured to thebolt constitutes th means whereby the bolt may be turned in order to move the frame 23 relative to the axle 28' when the bolts 27 have been loosened.

It will be noted that by this arrangement provision .is made for securing the parts 23 and 28 in fixed relation by'means of the bolts 27 which may be screwed up tightly, and that the bolt 32 constitutes an additional holding means, and also serves as a conven ient adjusting device. In order to provide for'the use of the member 23 below the axle 28, instead of above it, the lug 33' is provided, which lug is similar in all respects to the lug 33 and isadapted to cooperate with the bolt 32 in the same wa when the part 23 is used below the axle hen the part 23 is used below the axle itis of course neces sary to reverse the part 30.- The frame as shown, is made in skeletonj form for the urpose of lightness, and provided with various cross braces to stiffen 1t. This arrangement for lightening and stiffening may be varied to suit conditions. The frame is provided with the diver ing arms 35 adapted tojournal the ends 0 the, motor shaft in the roller. bearings 36. The angleof these arms at37- i's'so placed that when the removable endsv 38 of the motor are taken out, the (inner' parts of the motor may be moved out end consequent re-adjustments otherwise necparts 38 are fitted. This" facilitates the machining of the interior as a bearing bar of one diameter can be sent through to do all the work at one operation. As shown in Figure 4, the axle 28' 'is below the arms 25 but they may be reversed to suit conditions and if desired the arrangement may be modified so that the axle is above the arms '25.

The driving lmechanismconstitutes an important art of my invention, and is mostclearly siiown in Figure 3'taken in connection with the enlarged detail shown in Figures 5,6 and 7. As is usual in .motor vehicles, the vehicle wheels are each provided with a driving sprocket, which sprockets have chain connection to driving sprockets .on the motor shaft, between which driving sprockets a differential gear is provided. As shown in Figure 3, 39 and 40 are the drive sprockets on the motor'shaft 41. This-'motor shaft 41 is supported at its two ends by the roller bearings 36, and intermediate such ends by the roller bearings 42 secured to the removable motor casing ends 38. Provision is thus made for the proper support "of theshaft along itsen- 'tire length, and each sprocket drive is supported at two points on opposite'sides thereof and comparatively adj acent.. The sprocket 40 is'keyed to the shaft Outside of the;

motor shaft 41 is the drive sleeve 43,10 Q

which, the motorarmature. is secured, and which is' therefore the .primaiyfiflriving elenient of. the constructio second sleeve 44 independent of the-fir sleeve is mounted upon the right hand end of the shaft 41, and to this sleeve is keyed the sprocket drive 39. The reduction gear and the differential gear hereinafter described; and shown to. the

right of the motor in Figure 3 constitutes the connecting train of gearing between. the drive sleeve 43 and the shaft 41 and the sleeve 44.. The train of gearing includes casing 45 intermediate the sleeve 43 and sleeve 44 which casing is revolubly mounted upon the shaft 41 and carries the shafts and casing of the differential gearing 46. This diflerential'gearing 46 is in,the' main of a common type, and 7 consists as shown in Figures 3, 5 and6 of'the two pairs ofgears 4'7, 4'7, and 48, 48, mounted upoin the shafts 4 9, which are carried by the casing 45, and one of each pair meshes with the gear 50 secured to tli e'j sleeve 44 and the other of each pair meshes with the gear 51 zkeyed to the shaft 41, sothat one gear of each set drives the sprocket 39 on the sleeve 44 and the other two gears drive the sprocket 40 which is keyed to the motorshaft 41. In

-this portion 58 as a order to effect the desired reduction in speed the arrangement of gears shown to the left of the differential gearing and in detail in Figures 5 and 7 is provided. This gearing consists of a pair of pinions mounted on axes 53. which axes are secured in l'iearings projecting from the casing 54 of the roller bearing 42. of the internal gear 55 secured on the revoluble casing 45 and the gear 56 keyed to the driving sleeve 43. From the above construction it will be apparent that when the drive sleeve 43 is actuated by means of the motor armatures the gear at) in revolved, which motion is transmitted through the pinions .72 to the internal gears 55, thereby revolving the casing 45 which is journaled (.n the shaft l1. The revolution of the casing 43 carries with it the axes of the differential pinions 47 and 48. a part of which engage the gear 51 keyed to the shaft -11 thereby actuating the sprocket 4t), and the other of which engage the gear 50. thereby operating the sleeve it 'and the sprocket 3t It will be seen therefore that two reductions of speed may be secured. the first by the difference in size between the sprockets on the motor shaft and vehicle wheels, and the second by means of the reduction gearing 54". 52, 56. As the motor shaft 41 moves relatively to the sleeve 43. sleeve 44 and casing 45, the points of contact of the shaft with these members are provided w ith bushings 57, as clearly shown in Figure Other bushings between the shaft 41 and sleeve 44 may be provided as required. As shown in Figure 7, two pinions 52 are used in the reduction gear. but it is apparent that if desired this arrangement might be modified to use any number of intermediate pinions desired. The dimensions of the gears to secure any desired reduction might also be varied. Also as described and illustrated. the supports for the axes of the pinions 52 are secured to the casing 54 of the roller bearing 42. It will be apparent that if desired the support might be modified so as to extend from some other point than the part 54. as for instance from the diverging arms 35. As shown in Figures 3 and the casing 45 is provided with an outer portion 58 separated from thc.inner periphery of.such casing by a slight distance. It is proposed to utilize braking surface for a band brake to be applied in the usual way from the brake shaft 55). the operative connections for which extend to the front of the vehicle in the usual way. As shown the braking surface 58 is separated from the base of the gear 5.3 by an air space 58 adapted to prevent undue heating of the gear. If desired, a brake may be also applied to the drive sleeve 43 by means of the drum (to to which the band may be applied fr m the shaft 59 in the usual way. The

brake shaft 59 may also be connected to the usual wheel brake band til. (see Figure It will be apparent that the reduction gear as just described constitutes a very compact and efficient mechanism, easily protected fl'cll) dirt and dust and if so desired can be made to run in o l.

As previously stated. the differential gearing is broadly old, but certain features thereof are considered new, one of which features consist in the means for mounting the pinions 47 and -18. These pinions are mounted on the bearing pins 49. These pins are provided with a central bearing portion (3?) on which the gear is adapted to turn. and with reduced end portions having shoulders for hearing against the casing. The left hand end of the bearing pin as shown in Figure 5 is screw threaded and provided with a holding nut 4 and a cotter (if). It will be apparent that the bearing pin is securely held at both ends and that the arrangement affords a convenient and effective means for journaling the gear. The general arrangement whereby the differential is mounted on the through shaft 4' and whereby the supporting casing (36 supports the gears is also novel and advantageous. The part 4.3 against which the casing ('16 is secured turned down to form a recess as indicated at 67. thereby insuring an exact central portion of the casing 66 and a proper alinement of the axis of the gears. For disasseml'iling the arrangement is convenient as any gear in the differential may be removed without disturbing any of the others by simply taking off the casing 66 and slipping off the desired gears.

I have heretofore set forth the preferred form of my invention, but it will be apparent to those skilled in the art that various changes and modifications as to form and proportion may be made without departing from the spirit of the invention, which invention is set forth in terms coincident with its breadth in the following claims.
